Coincident Triumph Extreme Signature Loudspeakers
A versatile, transparent sound for the best high-end systems.Review By Tom Lyle

If
one has the pleasure of auditioning a pair of two-way, stand mounted Triumph
Signature Extremes, I strongly, strongly recommend inquiring if these speakers
have been fully broken in. In my
listening room it took at least two hundred hours (for those who do not want to
do the math this equals more than eight days of continuous use) before they even
began to sound their best. Before that time the frequency extremes did not
approach anywhere near their full potential, and their overall sound was rather
un-involving.

When they finally settled in they morphed into one of the most
responsive pieces of hi-fi equipment I have ever heard  that is, these
speakers from Coincident Speaker Technologies (CST) were almost totally
dependent on upstream components, and especially the quality of the recording,
in determining their sound. Even the most seemingly insignificant change in
set-up, a recording's attributes (or lack thereof), or the arrangement of
associated gear was audible. Lest one think that this would be a liability when
listening to less than perfectly recorded material, because these extremely
speedy and transparent speakers are also some of the most musical two-ways
I've heard, letting the quality of the recorded performance
shine through  and since you and I only listen to good music (naturally) the content
of the recordings compensated for any deficiencies in a disc's production.

UpdateThe Triumph Signature Extreme is an update of CST's
positively received Triumph Signature UHS. Although it uses the same woofer, it
is a very high-sensitivity driver. It has a specially treated paper cone that is
intended to reduce resonances yet at the same time is capable of, in CST's
words, "extraordinary resolution of detail". It has a large magnet assembly
that aids in providing its high sensitivity, low distortion, and at the same
time being able to handle high levels of power. The new higher sensitivity
1-inch
silk dome tweeter is a "special" version of a Scanspeak Revelator tweeter,
which is the same unit used in their more expensive Eclipse series of speakers.
The internal wiring now use's CST's TRS Extreme, which is the same wire that
is used in their Statement and Total Victory II. Also, the crossover has been
modified to take advantage of these improvements. To top things off, the Triumph
Signature Extreme's relatively large 16 high by 9 wide by
11.5 deep (in inches) cabinet has "extensive" bracing to "create an enclosure as
rigid and inert as possible".

The Extreme's took up residence in my second system that
uses a pair of 70-Watt vacuum tubed PrimaLuna ProLogue Six monoblock power
amplifiers. The preamplifiers were either a tubed Balanced Audio Technology
VK-3i or VK-3iX, and at times an Audiobuoy Scorpion. Digital sources were an
Arcam CD player used with and without a Benchmark DAC1PRE digital converter, and
an Oppo universal player. During the second half of the review period I
connected an Artimus SA-1 turntable with a Lyra Helikon cartridge mounted on a
Tri-planar tonearm with a Lehmann Black Cube SE performing phono preamplifier
duties. Everything except for the hardwired tonearm was hooked up with a
rotating array of MIT, Cardas, Monster, and Kimber cable.

The Extreme's were shipped with their matching stands that
retail for $230. I was skeptical  how could relatively inexpensive,
self-assembled stands with MDF pillars be any good? Well, as it turns out, very
good. The heavy top and bottom steel plates kept everything extremely stable,
and as a bonus the stands are also very good-looking. Both spikes and hard
rubber feet are provided, and the later held the stands in place on our hardwood
floor very well  the speaker/stand combination wasn't going anywhere.

The Extremes do not have any grills protecting the drivers.
This didn't bother me that much, but I was concerned that curiosity would get
the best of my nine year-old daughter and she would damage the speakers. My
worries about her ended up being for naught  although I had to caution some adults
more than once when their inquisitive fingers were inches from the
tweeter's dome. Groan.

My FavoriteEarly in my listening sessions after the Extremes finally
broke in I hit play on one of my favorite small ensemble classical CDs in my
collection, a chamber arrangement of Shostakovich's 15th
Symphony performed by violinist Gidon Kremer and friends in his
Kremerata Musica. This performance on DG features violin, cello, celesta, and
percussion, and is superb not only because it sounds great, but also it is a
great performance of a great piece of music. The most noteworthy aspect of the
recording that the speakers revealed was the acoustic of the hall, a fantastic
sounding small church (I suppose) in Germany. Not only was the sound of the hall evident, including its clearly drawn
dimensions  but also the air surrounding each instrument in its space in the
soundstage, and thus, the actual performance space in which the musicians were
performing. I could sense the relative size of each instrument from the sonic
aura around the instrument and its relation to the size of the space. From the
strike of the sparkling bells at the opening of the first movement to the final
notes of the last movement things sounded spooky real. It was hard to believe
this sound was emanating from conventional drivers in a small ported cabinet.
The midrange was the star of the show, with the rosiny strings, bell-like
celesta, middle ranges of the piano, and of course the sound of the hall
exhibiting these essential frequencies. It was not only an accurate portrayal of
the performance, but created a direct link between the recording, my ears, and
my brain.

The stated low frequency response of the speakers is 45 Hz,
which was low enough for the bass drum and timpani whacks to reasonably convey a
sense of heft, and to suggest that there was a considerable amount of air moved
in the recording venue. I informally tested the speaker's frequency response
and got readings into the mid 40s as CST specified, but things dropped off
steeply below that. The cabinets of these two-ways is relatively large for a "small" two-way, so I was surprised that I couldn't get more bass out of
them, and this was surely their greatest (if only, really) weakness. But thanks
to the very tight sounding upper bass the low end was extremely punchy and pitch
stable. The missing lowest octave didn't detract from the reduced forces
playing this very alluring arrangement of the Shostakovich masterpiece.

Later in the review period I played a few tracks from
clarinetist Don Byron's A Fine Line
release on Blue Note that features different singers performing arias and
standards. On the Stephen Sondheim tune The
Ladies Who Lunch Cassandra Wilson's vocals seemed to reflect the
sound of the particular microphone and the reverb effects used at New York
City's Avatar Studios as much as her vocal talent. Yet the Extreme's
transparency combined with its exceptional musicality made obvious that her
commanding voice could easily prevail over any limits of the technology. When
comparing it with some reference discs it was easy to tell that the slight
cupped-hand coloration was the fault of the recording. Later, when I skipped
back to the first track, "Check Up", the Ornette Coleman tune with wordless
vocals by Mark Ledford, the inaccuracy I spoke of on the Cassandra Wilson cut
was nowhere to be found, and in its place was a sound that was much more
unaffected. Was it recorded on a different day with a different mic? Whatever
the cause, the Extreme's made the incongruity between sessions obvious.
Throughout the entire album the speakers kept their composure, sorting out the
intricate support of the band, most notably Uri Caine on piano behind Byron's
clarinet. Paulo Braga's drums and various percussion were spread out across
the man-made soundstage, and even though the piano was also spread out within
the same margins of the stage, each occupied distinct areas within it.
Bryon's clarinet was panned hard left, and details such as the sound of his
keys hitting the instrument's barrel made things all that more convincing.

What I wasn't expecting was how much I enjoyed time spent
listening to these speakers with what I previously thought of as less than
stellar recordings. I'm not saying that the Extremes euphonically colored the
sound to make crummy recordings sound "good"  poorly recorded or poorly
pressed records and CDs were revealed as such. But the speakers clearly
exhibited that the musicians and engineers had the best intentions when making
these recordings. I would like to think that there are few that set out to make
a poorly recorded or otherwise produced product, and the Extremes brought to
light their intentions, misguided as they may have been. So, even though I've
played this record constantly since I was about 15 years old, I was shocked when
I played the 1968 live recording at the Forum in Los Angeles of the Howlin'
Wolf penned "Sitting On Top Of The World" on Cream's Goodbye
album.

Here I was, enjoying a record I'm used to hearing on huge speakers at
nearly the volume it was originally played on stage, and enjoying it as much,
nay, more than I ever had before. Sure, the Extremes can pump out some serious
SPLs, but even when I played the track back on a low-ish volume the close
mic'ing didn't really make me feel as if I was at the actual event, but it
sure brought me close to the feeling as if I was sitting in the room where they
were mixing the tape. Even though this recording hardly approaches what would be
termed as "audiophile" or "reference", Eric Clapton's guitar amps were
there, and even though the drums
sounded quite rolled-off in the highs I could "see" engineering details in
my mind such as the distance between the drums and the microphones. Speaking of
mic'ing distance, I could sense Jack Bruce voice weaving in and out of the
microphone's sweet spot, which further brought me closer to the into the
recording's world, and thus, closer to the original event. And, by the way,
this live recording is the most intense rock versions of this song you'll ever
hear, and the Extremes made this quite obvious that this is a fact, not opinion.

I would be remiss in not making mention of the Triumph
Signature Extreme's stable impedance characteristics and especially its high
sensitivity. CST states in its specifications that the speakers can be driven
with as little as three Watts, and although I did not attempt using, for
example, a low-powered single-ended triode (SET) amplifier, I have no doubts
about their claim. Driving the speakers in my system with the sixty Watt per
channel PrimaLuna ProLogue Six monoblock amps were more than enough power, and
practically speaking, were almost overkill. What's more, the two tube
preamplifiers that I had on hand while the Extremes took up residence have
particularly black backgrounds; in fact they are two of the quietest preamps of
their ilk that have passed through my system in quite some time. Yet when using
the Extremes their behavior was even more unobtrusive -- their volume controls
were set at a much lower level than when using other speakers that I had in
house. This led to a blacker background and an increase perceived dynamics as
well as demanding less from the power amplifiers. Whether the speaker's
high sensitivity was the cause for the speakers to be so revealing when I
switched between different components and cables, I don't really know, but the
end result was that I sensed as if the speakers were competing to be the least
colored component in the chain.

Makes A PointIn
their advertisements and literature Coincident Speaker Technology makes a point
of highlighting their speaker's high sensitivity and uniform impedance
characteristics. But one shouldn't assume that these speakers are produced
solely to be nominated as darlings of the low-powered amplifier crowd. The
Extremes had no problems whatsoever handling some significant wattage when I
took them upstairs to the big rig using amps with a healthy 250 Wpc. They fared
very well indeed. And when mated with a sub-woofer they displayed their
potential for being monster satellite speakers. Their versatility combined with
their extremely (pun intended) transparent sound makes me very comfortable
recommending them for use in the best high-end systems, and also recommending
them for use in growing systems that will eventually be able to flaunt the
abilities of the associated equipment, and above all flaunt your excellent taste
in music.
